We are planning to have AIM/EPII cards on our 2600 series router. This is done particularly for VPN configurations. How does this card helps in the VPN ( complex math algoritms - encry and decry ) . Is it not possible to have VPN by having enterprise IOS version on the router withouot this cards. What I beleive is that Ent version of of IOS supports VPN configuration commands.
Please share the experience.
Thanks in advance.
